Do you like the 09 yz450f?

I am a woods guy but I have been thinking about picking up an older 450 to ride some moto every now and then. What is the general consensus of the 09, or even that whole generation of 450s?

They are a good reliable bike. Put a pro Moto billet end cap on it and let it rip.

With only a few mods, this bike is awesome, especially for a do-it-all machine. The 09 has some nice advantages...suspension, one of the most reliable bikes ever, quality, beefy parts like the bigger axles, very easy to work on (I jetted mine without even moving the carburetor), one of the most comfortable bikes I've ever ridden, and fairly light for a 450. With DRD exhaust, heavier flywheel, 06 cdi, taller handlebars, and basic protection (hand guards/skid plate), this bike is great for woods and track use. Very usable and fun to ride. Only other thing this bike could use for trails is WR gears.

I bought a used 09 450.  Love it. heavier flywheel gives it more usable power in the woods and not screaming out of a corner. The bike feels nimble and very reliable. You can't go wrong with a YZ

I have an 06 which is essentially the same, I love it. Its been the perfect bike for me, It is set up for the woods with a rekluse, heaver flywheel, WR Tank, hand guards, 18 inch rear wheel. I rarely ride it on the track but when I do it still performs great, at this point I can say this is the best bike I have ever owned and I have had pretty much every color of the rainbow except for orange.

This! Mine is pretty much stock and it rips but also works great on our fire roads and trails out here.

My 09 does great in woods,trails and the MX track!

Added a 9 oz fly wheel, bar risers, 06 cdi and complete oem 06 exhaust.

The 09 is a great bike but the handling is a bit lazy. If strictly MX have you thought about a 250f?

After reading all these good replies i have an 07 yz450f really love bike i have it set up for woods also but runs very hot usally 210-250 thats the highest ive seen just depends how fast im goin and outside temp does all ur guys run that hot

I have never checked the temp but yes in slow single track my 06 does get pretty warm. That just tells me that I am going to slow, pick up the pace and it cools back down  :rolleyes:

Really need to figure out how to not burn my pants on the power bomb header as well. 

Never had that trouble but i have the exhaust wrap on mine that could help

I bought a 2009 from a friend who had it set up really good for woods.  It took some $ to get it right but it is a fine trail bike, best I've ever ridden.  The only thing I miss is electric start but it starts easy, hot or cold.  With a full tank of gas it weighs 250 lbs loaded with everything you could want on a woods bike.  

 

Mods include radiator guards, hand guards, kickstand, coolant catch bottle, alum. skidplate, 18" rear wheel, heavy flywheel weight, o-ring chain, 18" rear wheel, Factory Connection revalve, Boyesen Supercooler oversized water pump, Scotts steering damper, and most importantly a Rekluse Core Exp 3.0 autoclutch.  The autoclutch really helps tame the beast.  I still use the clutch lever a lot so I installed a Motion Pro T3 Slidelight clutch cable which lightened the pull a considerable amount.  The Rekluse prevents stalling which was a problem without it.

 

The bike has never overheated on me but I keep it moving.  I think the oversize water pump helps. I occasionally boiled the gas but installed a heat shield under the tank and that cured it.

Sounds good man, i have the super cooler pump also and the temp stickers and then a tempurature radiator cap and its nt uncommon to see 240 to 250 degrees on an 75 to 80 degree day

I was there in NM right after he picked up that bike - he got a good deal on that very clean '09 - haven't talked to him in awhile, though. But that bike is at least part of the reason I'm seriously considering a move from my '11 WR to a woods set up '08 YZ450. Electric start sure is nice sometimes, but not a show-stopper for me.

Love my '09

The '09 is deservedly considered the best of the Gen2 YZ450F models.  The only reason to select an earlier one would be if there were concerns about wheel interchangeability with other older YZ's or a WR that you might already own.

Gray would this work? I have a 07 wheel I'd like to make work on my 09?

I wouldn't do it, no.
